METHOD OF DETECTING OPTICAL AND OPTOELECTRONIC SURVEILLANCE EQUIPMENT AND APPARATUS FOR REALISING SAID METHOD Russian patent published in 2014 - IPC G01S17/06 

FIELD: radio engineering, communication.

SUBSTANCE: invention can be used in systems for detecting optical and optoelectronic surveillance equipment in natural conditions and identification thereof. The method comprises, before probing, receiving natural background radiation signals by measuring radiation spectral distribution and determining therein the ratio between intensities of spectral components at three selected wavelengths; generating laser radiation beams at said wavelengths with beam intensity ratio matching the spectral component intensity ratio in the received background radiation; generating a resultant laser radiation beam and performing probing and receiving reflected laser radiation at the three wavelengths and in a wide spectral band; measuring the strength of the received optical signals and determining retroreflection factors for the three wavelengths and for a wide wavelength band; based on said values, forming a spectral portrait of the retroreflection factor, from which optical and optoelectronic surveillance equipment is detected and identified.

EFFECT: high probability of detecting and identifying optical and optoelectronic devices and surveillance equipment and determining association thereof with known classes of optoelectronic devices.
